Abstarct: Nowadays the mineral resources cannot be identified exclusively using surface geological information. Geophysical methods are of the proper ones that are efficient in reconnaissance of mineral resources. The aim of this research is to detect the probable subsurface copper anomalies in Asemanoo mineral index using three geophysical methods. They are electrical resistivity (RES), induced polarization (IP) and very-low-frequency electromagnetic (VLF-EM) methods. In this study it is attempt to identify the prospective copper mineralized zones and to propose the best drilling locations by measuring, processing, modelling and interpretation of geophysical data. To achieve the goals, three parallel profiles each with 220m length in NS direction and another profile in E-W direction have been designed to measure geophysical data. The resistivity and induced polarization surveys have been performed using dipole-dipole array. In addition the VLF measurements were taken in 5m spacing on the same profiles. The geo-electrical data was then inversely modeled by Res2DINV and ZondRes2D software. The VLF data also were considered qualitatively and quantitatively. To get a better view of the region and lixnk the obtained results, the three dimensional (3D) illustrations of various data were provided using Voxler and ZondRes3D software. The obtained results indicate that studied region (Asemanoo mineral index) has many faults along with NE_SW and also this part of my study has probable of seam and scatter copper deposit in N_S at the depth of more than 20m . At the end the optimized drilling points for direct study of mineralization in the region were presented.
